          Description

          Hello,

          I'm using the Kurento image from the lab (kurento-image-R5.0.33
          <https://cloud.lab.fi-ware.org/#nova/images/7af4b98a-2528-4114-9614-b8879e033811>
          ).

          After deploy the machine and connection by ssh, i use the command "mvn
          compile exec:java" to deploy the example "kurento-hello-world".
          The application doesn't deploy and if the user press th "Ctrl" + "c" it
          prints an error blocking the shell, as show in the following code:

          root@kurento:~/kurento-tutorial-java/kurento-hello-world# mvn compile
          exec:java

              The application is started when you see the following line

              [App.main()] INFO - o.k.tutorial.groupcall.GroupCallApp - Started GroupCallApp in 10.624 seconds (JVM running for 30.12)

              It takes very little time, but in virtual machines you should add the flag 

              -Djava.security.egd=file:/dev/./urandom

              so that Tomcat may start as usual. You can read more about this here. We've already made a note in our documentation about this, and will be included in the next release of the docs.

              About pressing ctrl + c, you are seeing that error because you interrupted the startup process.

              Please give it a try with the aforementioned flag, and see if it deploys correctly.

              Hello,

              Just try to use the flag and the deploy work properly.
              The ctrl+c problem was indeed an error of the interruption of the start-up process and doesn't appear any more.

              Please remember to change the Kurento image that is available on the Lab, for the next release, or add a note in the documentation section.

              Best regards.

              We have changed all the startup scripts for the tutorials with that flag, and will add a note in the documentation about this issue.

              The image is going to be updated for the new version of kurento-5.0.4 and while the tutorials are not preinstalled, they will be available for downlad with that flag added.

              Regards
